Application filed November 25, 19077 lib all; whom it may concern:

lie it ltnowuthat we, ln'lnn U. PATTERSON and Joni: .l. l loix, both ofMcKeesport,

Allegheny county, Pennsylvania, have inrented a new and useful TumblingApparatus, of which the following is a full, clear, and exactdescription, reference being had to the aeooni p an ying drawings,forming part of this specification, in which lligure l is a top planView showing one form of our improved apparatus ;v Fig. 2 is a verticalcross section; and Figs. 3' and 4: are detail views showing differentpositions of the barrel and lid.

tini- 'nvention relates to the class of tu1ntiling barrels and isparticularly"designed for t'uniblingpipes or tubes though it may beemployed for other purposes.

'l'he object'of the invention is to provide simple and cilicientmechanism for feeding the tubes or other material into the barrel, topriii'vide for side charging of an barrel and also to provide mechanicalmeans for (1h hip;- the lid and discharging the tumbled material. i

in the drawing .2 represents the tumbling barrel which may be made insectional form and is provided at its ends withanmllar bearings ii whichrest upon rollersl, 4 suitably lll"l.illi'(tl on the foundation 5. Aninieningr is yuorided in the side of the barrel nhich is of therequisite length to receive the pipes or material. this opening being;

ing arms 17 which extend beyond the rails and to a point adjacent tothebarrel surface. "We have shown fillers secured to opposite sides of therail webs, the arms being pivoted through these fillers and through therail and a roller 18 is preferably positioned between the two sidepieces of each swinging arm. Upon a shaft wtextending lengthwise of thestorage table or slcidway are placed star wheels 20 which may beprovided with projecting arms; and the shaft 19 is connected throughslow motion gearing 21 and 22 with an electric motor In the use of theapparatus the pipe or other material to be tumbled is fed upon thestorage table and rests against the arms of the star wheels as showninFig. 2. W hen it is desired to stop the barrel it is brought to theposition shown in Fig. 3 with, the lid open by rotating it in aclockwise manner. The shaft 19 is then turned slowly by actuating themotor 23 and the star wheels are turned far enough to allow the loadbetween two of the arms to roll down the skidway from the swing arms andinto the barrel through the side opening. The barrel is then rotatedslowly until the lid or door lifts the swinging arms and passes upwardlybeyond them; The arms then drop back against the lower stops 24 and therotation of the barrel is then reversed in a. counter-clockwisedii'iary-inanner, preferably in a counter-clock wise direction, untilthe tumbling is completed. It is stopped with the lid up pern'lost andthe lid fastening is then detached when the barrel 1S rotated half wayaround in a clockwise direction, thus allowing the pipes,

scale, etc, to drop out into the cradle. The

barrel is then turned: into the position shown in Fig. 8 and theoperation is repeated.

The advantages of our invention \Vlll be apparent to those skilled intheart. The

end feeding of. the barrel by hand is done away with and a. properloadis picked up and fed automatically intothe barrel at each partialturn ofthe star wheels. The lid is closed by therctation of the machinein con-- unet1on 'Wlllll the swing ng arms and the barrel is selfcleaning, as both the material to be cleanedandthe scale and dirt dropout when thebarrolis turned.upsidedown. The,

load may be easily lifted from the cradle by an overhead crane or othersnitablemeehanism. Many other changes may be made in the form andar'angement of the barrel driving mechanism also in the storage tableand feeding means, without departing from our invention.

We cla 1m 1. In apparatus for tumbling pipes and similar articles, thecombination with a tumbling barrel having an inletand outlet opening inits side and a storage rack extending alongside the barrel, of mechanismarranged to transfer a predetermined munand a star wheel feed devicearrangedto de posit successive loads in the barrel; substantially asdescribed.

4-. A tumbling barrel having a side opening, a hinged closure therefor,and mechanism aranged to turn the closure into its closing position whenthe barrel is rotated in one direction, and to permit. rotation of thebarrel in the oposite direction with the closure in its open position;substantially as described.
